摘要 针对分集合并技术中低复杂度与高性能之间存在的矛盾,将选择合并(SC)与切换驻留合并(SSC)相结合,提出一种新的混合合并方式SSC-SC,并对瑞利信道下2L个独立同分布分支的SSC-SC系统进行研究,给出了平均输出信噪比SNR、误码率BER、电平交叉率LCR和平均中断时间AOD的闭合表达式。最后将SSC-SC与选择合并和广义选择合并(GSC)进行比较,结果表明SSC-SC性能稍差,但在可以接受的范围内,而其最大特点是结构简单、易于实现、节约资源,具有良好的实际应用价值。 Low-complexity and high-performance of diversity combing schemes always conflict. A new hybrid combining technique named SSC-SC is proposed,which is composed of Selection Combining ( SC) and Switch-and-Stay Combining ( SSC) . The SSC-SC scheme with 2L branches in Rayleigh fading channel is studied. The closed-form expressions for the average output Signal-to-Noise Ratio ( SNR) ,Bit Error Ratio ( BER) ,Level Crossing Rate ( LCR) and Average Output Duration ( AOD) of the SSC-SC system are provided. Finally,the proposed SSC-SC is compared with SC and with Generalized Selection Combining ( GSC) . Results show that the performance of SSC-SC is not as good as that of SC and GSC but is still acceptable. From the standpoint of implementation,SSC-SC is characterized by simple structure,easy realization and resources saving. With these characteristics,SSC-SC is feasible for practical application.
